Description

There is the floor drain flowing into funnel

Technical field

The present invention relates to a kind of floor drain for exporting to from the ground Jiang Shui that can pass through in waste pipe, such as, for the floor drain of shower set.

Background technology

Usually, the water occurred when shower is collected by discharger and downward guiding is continued on the ground of and then standing relative to the people just in shower.Discharger is called floor drain below.Described discharger is not in the being forced property people that the is arranged on shower ground region of standing, but such as must can be arranged on ground region side herein yet, is adjacently built in wall, sometimes also referred to as dewatering installation on wall with this ground region.When in water on the wall dewatering installation downwards instead of side direction derives time, so dewatering installation also can be regarded as floor drain on this wall.Certainly, the floor drain preferably outside wall, comprises the floor drain near wall.

In addition, the floor drain in following meaning being discussed here, that is, deriving water from the ground that can pass through, is not such as derive water from wash basin or kitchen sink in other words.Fountain or Shower treadle are regarded as the ground that can pass through; The bottom of bathtub is not the ground that can pass through.

Floor drain is known and extensive use already.These floor drains are the floor drain worked in " point-like " to a certain extent, and the horizontal zone of limited stretch controlled by this floor drain, is wherein typically provided with inclined-plane water being guided into floor drain around ground.Common also has so-called slot type dewatering installation, and this slot type dewatering installation extends farther along the direction that a horizontal direction is more vertical with this horizontal direction than edge, and collects water by groove.There is such flexible program for this slot type dewatering installation, described flexible program has usually the visually covered and pond for collecting water of substantially whole longitudinal extension distribution along slot type dewatering installation.Nearest also known such flexible program, wherein, groove is open upwards and is only made up of the groove body observed from above slightly in spill in the major part of its longitudinal extension, and water for collecting water, and is directed to real dewatering installation by described groove body.Here " real " dewatering installation is obviously short than groove on the longitudinal extension direction of groove.Embodiments of the invention just belong to this type.

Under any circumstance, floor drain all should according to the structural fringe conditions location determined, fixing and sealing.With the mating of possible slope, ground, the mating of vertical wall that may evenly adjoin with dewatering installation, with the mating of tile patterns, with ground construction height (i.e. the construction height of such as seamless floor and floor covering) mate and with the mating of the sealing device of surrounding, calculate in described fringe conditions.

Summary of the invention

The object of the invention is, provide a kind of floor drain, described floor drain improves to some extent in the flexibility of installing.

Described object is realized by a kind of floor drain for being exported in waste pipe by the ground that can pass through by water, and described floor drain has:

Flow into funnel, described inflow funnel has the union of downside and the containing pipe for union, wherein, union can insert in containing pipe from above, to pass through containing pipe from ground control water, and union can rotate in the orientation insertion containing pipe of 180 ° around vertical axis with at least two relatively, it is characterized in that, described vertical axis is arranged so prejudicially relative to the top above described union flowing into funnel, makes to change inflow funnel in the position in a lateral direction of level by rotating 180 ° relative to containing pipe.

Preferred form of implementation provides in the dependent claims and describes in detail below.In the scope of current effective claim 1, it is also main contents of the present invention that each feature combines by other means; This is also applicable to embodiment.

Here alleged inflow funnel also has union also referred to as drainage cup in the prior art sometimes on its underside, and described union should derive the water collecting in and flow in funnel top.Therefore described top expanded relative in union at least one horizontal direction in cross-section.Described inflow funnel can be the described elongated pond of slot type dewatering installation or the middle section of slot type dewatering installation, carries water by the groove structure be open upwards to described middle section.Discuss in the present invention and flow into funnel because described inflow funnel from the top of expansion towards union funneling attenuate, and other parts of floor drain can be inserted downwards with union in addition.

Here should point out tout court, orientation illustrate as " on ", D score, " vertically ", " level " etc. yes for the installation site conformed with the regulations, but the theme of claim is not limited only to the floor drain of installation.On the contrary, the synergy relation of each element of this floor drain should be described in general manner, wherein orientation illustrate just for illustration of, be not substantially limit corresponding element only to be protected in described position.

Union inserts floor drain parts wherein referred to herein as containing pipe, and for water is flowed to waste pipe.Described containing pipe can be such as syphon, and described syphon guarantees closed smell by common mode on the one hand, and first deflects a right angle around vertical accommodation direction on the other hand, then arrives on the joint of the waste water pipe of level continuity.Disclose the socket connection between union and described containing pipe flowing into funnel in the prior art, here only because two usual columniform geometries of parts have just achieved the rotatability around vertical axis.

In this case, this rotatability is utilized in a particular manner.But first will determine, a this rotatability in principle needs exists with the form of twin-stage, and the rotatability of progression higher here or complete (arbitrarily) can't cause interference, but preferably.Because the top that flows into the now funnel vertical axis about this rotatability is arranged prejudicially relative to union, the rotation of 180 ° causes lateral shift in the horizontal direction, offsets the twice size of eccentricity in other words.

Rotatability is not to make union can rotate in containing pipe usually.As long as union also can insert just much of that in the position of rotation 180 °.

Owing to flowing into the position of that floor drain determined usually by funnel and interface on floor covering or like surperficial visible part, therefore there is controllability at least one direction.The order of magnitude of preferred eccentricity (correspondingly has when rotated and doubles effect) in the scope of 2mm to 20mm, and its lower limit is more and more preferred in the following order: 3mm, 4mm and 5mm, and using 17.5mm, 15mm and 12.5 as the upper limit.

After rotation 180 ° ground is installed, flow into the top of funnel with double numerical value horizontal-shift.In this simple situation, such as, should consider the predetermined condition of the ceramic tile patterns aspect that will mate, the thickness of ceramic tile in horizontal wall that floor drain should evenly connect or consider other geometrical boundary conditions prespecified in the horizontal direction.

In a preferred form of implementation of the present invention, the controllability just illustrated is set as coarse adjustment and can be supplemented by accurate adjustment.Accurate adjustment particularly can be achieved like this, that is, the horizontal direction of union along at least one level in containing pipe flowing into funnel has gap slightly.If this horizontal direction is corresponding to the direction that there is described eccentricity, and if described gap is preferably roughly equivalent to described eccentricity, then due to described gap, can carry out stepless accurate adjustment around two positions prespecified by eccentricity, wherein each accurate adjustment region adjoins each other when gap is consistent with eccentricity.

There is gap owing to inserting between the union of containing pipe and described containing pipe, as long as water is not aspirated when discharging, usually there will not be sealing problem.Additionally covering can be set on the upside of gutter, also will be described after this.Finally, the sealing requirements for floor drain limits generally like this, that is, the upper end of possible current out position, particularly containing pipe, is positioned at the top of the sealing plane on ground.Yet will be described in detail to this.

Described gap is preferably formed two-dimensionally, also the fringe conditions that vertical eccentric degree direction exists can be taken into account.Here to point out, gap at the preferred feature in a lateral direction of at least one level in principle independent of the direction of eccentricity, the adjustability namely realized by eccentricity can by by along another direction, the adjustability that realizes of particularly vertical with eccentricity gap combines.But the preferably gap of two dimension, one in the wherein said direction accurate adjustment carried out for the coarse adjustment realized with respect to eccentricity.

Advantageously can on union inserting retainer ring, when being inserted in containing pipe by union, described retainer ring is used as backstop thus serve as size adjustment part.Cause the cavity formed additionally can upwards be capped by gap, and play certain sealing function as mentioned above thus.

In another preferred form of implementation, union has such external cross section profile about the cutting plane of level, and described external cross section profile is at least different from circle by smooth portion's section.When remaining profile is circular arc, described smooth portion's section is secant.Described smooth portion's section has certain relation with the design scheme on the top flowing into funnel, in other words the top of described inflow funnel (namely with described smooth portion's section vertically) in corresponding horizontal direction should not protrude from described smooth portion's section significantly, exactly, (in said direction) outstanding the highest preferably reaches 20% of union diameter, and particularly preferably outstanding 15%, 10% or only outstanding 5%.Reasonably, now stagger towards opposite side relative to vertical eccentric axis in the top flowing into funnel.

Particularly when floor drain should as far as possible near above containing pipe for the important border of union, namely install near vertical wall time, this form of implementation is favourable.By described smooth portion's section with flow into the corresponding not outstanding design scheme in funnel top, now described border exceedes containing pipe and stretches out a segment distance, and can not make to load and to take out inflow funnel.Described border also can extend to the described smooth portion's section of next-door neighbour or flow into funnel.In order to illustrate that this situation is see detailed description of the invention part.

Thus, combine with described eccentricity and the gap if desired with union in containing pipe, containing pipe (and the parts connected thereon) can partly be mounted into below described border, such as vertical wall, and at the best of times only also need the size considering the visible part of floor drain in floor surface here, described floor surface therefore can be almost concordant with described border.

Described smooth portion's section must not be straight here, but this is preferred.Described smooth portion's section also can slightly bend, but has the radius of curvature of all the other bends being obviously greater than union and containing pipe.

Described containing pipe is not preferably upwards stop with union simply, but has the structure horizontally outward extended from union, and described structure is referred to herein as flange.Flange described here must not be smooth, and described flange neither intactly extend around gutter.But as shown in the Examples, these 2 is all preferred, its flange equally preferably but be not necessarily arranged on the upper end of containing pipe.Here flange edge transition portion therein can proceed to containing pipe with chamfering, to be convenient to ingress pipe joint.

Preferably on flange, install sealing mat, described sealing mat is flexible and preferably can turns up, to seal the surf zone around flange, and so that preferably with continuity, the diaphragm seal that such as covers whole shower region or sealing mat be connected.A favourable form of implementation setting, sealing pad is preferably injection-moulded on flange in upside.

Due to described sealing mat, such as make perfectly to seal between containing pipe and union, and such as also have the perfection sealing be connected between the parts that flow on funnel flowing into funnel and floor drain, no longer extremely important, this is favourable in a lot of and achieves flexibility.

Flow into funnel and there is the inflow entrance be open upwards, to derive water.This inflow entrance hides at least in part preferably by visible cover plate (Sichtabdeckung), can not produce obviously interference to aesthetic outward appearance.Here, such as, in cover plate or laterally, gap can be reserved on cover plate side, to allow water to flow through.Preferred described cover plate assembles like this, this cover plate can be rotated in the orientation of 180 ° relatively two (being also about vertical axis) and install.This has such advantage, if that is, cover plate is not must must be designed to even numbers symmetry---and the shape of cover plate or its decorative pattern comprise words identification.In other words, when being flowed into funnel by rotation and utilizing according to controllability of the present invention, cover plate still can be installed with the orientation of hope relative to room, such as avoids in other words, and decorative pattern or words identification " turn upside down " thus.

Another form of implementation is provided with the comb inserts on the cover board from cover plate to downward-extension, and described comb inserts is used as strainer or the screen cloth of dirt, particularly hair in water.As its name suggests, described comb inserts has comb-shaped structure, in other words shaft-like or arching, and the longitudinal direction of described structure at least has main component in the horizontal direction, is preferably in horizontal direction.Now particularly hair to hang on these comb teeth and is easy to be eliminated.In other words comb tooth comb ground distribution to a certain extent, wherein, described comb tooth is preferably arranged to comb from common matrix respectively towards two contrary sides.

In addition comb tooth is preferably distributed on multiple horizontal plane, is not in other words to be all distributed on identical vertical height.In this embodiment, there is the horizontal plane that three have four comb teeth respectively, wherein every two comb teeth are outstanding towards side.According to another preferred form of implementation, comb tooth in Different Plane staggers mutually, in other words, two comb teeth of a such as plane are not the tops of two comb teeth of the plane be accurately positioned at below it, and accurately neither be located thereon the below of two comb teeth of the plane in face.Finally, relative to vertical cutting plane, these comb teeth have obviously high cross-sectional profiles, are highly greater than width in other words, and preferred heights is at least twice of width, and particularly preferably height is at least three times of width.Here comb tooth can tilt (now, highly referring to the direction tilted relative to vertical direction) when considering main flow direction relative to vertical direction slightly.The also reference example to this.

So far, controllability in the horizontal direction is mainly described.But according to the present invention, also other controllability can be set.As already described, union can insert with the different degree of depth and receive in pipe, and wherein retainer ring can determine the described degree of depth.Thus achieve simple and preferred height adjustability; In other words can carry out with the height on the final surface on ground adaptive in this form.For this reason by described form flow into funnel and all be connected to flow between parts (such as groove) on funnel and containing pipe and all parts (such as smell seals and waste pipe) be connected on containing pipe vertically regulate.

Another adjustability also relates to horizontal dimension, but relates to the total length of preferred shower groove in this case.May it is desirable for and carry out independent adaptation to this length, this is such as because shower groove evenly should to extend in both sides or should be suitable with ceramic tile patterns between the walls at two.Here preferably set, shower groove dewatering installation according to the present invention, outside inflow funnel, in other words in the horizontal direction on inflow funnel side, particularly has in the both sides flowing into funnel the groove section bar be open upwards.This groove section bar now by shortening simply, such as, is sawed short, and adaptive individually.If desired can the simple end segments of inserting, to install visual closure and to consider that the shape of spill common for groove installs the wall portion closed, see embodiment.

Accompanying drawing explanation

Describe the present invention in detail according to an embodiment below, wherein as already noted, other combinations of each feature in claim 1 also can be essential places of the present invention.Specifically:

Fig. 1 illustrates the decomposition diagram of the floor drain according to channel away of the present invention, but does not wherein have containing pipe, flange and sealing mat;

That Fig. 2 illustrates the be in assembling form corresponding with Fig. 1 and the stereogram of floor drain with containing pipe, flange and sealing mat;

The floor drain of Fig. 2 when Fig. 3 illustrates that sealing mat is dug;

Fig. 4 illustrates the sectional view of floor drain with vertical cutting plane, and this floor drain is in the state adjoining installation with wall;

The top view of Fig. 4 situation shown in the lower area of Fig. 5, upper area illustrates sectional view with horizontal plane.

Detailed description of the invention

Fig. 1 illustrates the floor drain according to channel away of the present invention.Here Reference numeral 1 represents inflow funnel, and the downside of described inflow funnel has union 2, has the top 3 of expansion above union.Union 2 has the cross-sectional profiles shape of scabbling to left front, and this cross-sectional profiles shape also will describe in detail according to Fig. 4 and Fig. 5.Below union, show retainer ring 4, retainer ring and described contour shape suitable and can overlap hermetically and be inserted on union 2.

Above union 2, the top 3 flowing into the expansion of funnel 1 is stretched out to right front with to left back relative to union, forms the peviform shape with rectangular base outline thus.On top 3 to left back and be open upwards to right front connection, the groove 5 that is made up of profile material; The top 3 flowing into funnel 1 is substantially limited in being shown as in the region of interruption in the contour shape of groove 5 on the longitudinal direction of described groove 5.The lath 6 of two rectangles is provided with in groove 5.The outer end of groove 5 there are two plastic end enclosures 7 for this reason.

Two groove section bar parts 5 are actually one here and link up, and in other words, connected by the outer panel that longitudinally side extends continuously in central authorities, only have the interlude of rectangle to be punched, flow into funnel 1 to hold, accommodation specifically flows into the top 3 of funnel.Continuous print plate has the card interface of rectangle, and flow into corresponding clamping projection on funnel 1 top 3 and can be scarfed in described card interface, this is shown in Figure 1.

Can easily imagine, groove profile sections 5 collects water from the ground that can pass through under the assembling and installment state of floor drain, and described ground roughly evenly adjoins with the upside of longitudinal seamed edge of groove section bar 5.Described water flows into the top 3 of described inflow funnel 1 in central authorities due to not shown little drift angle and is imported into union 2 by the basin shape shape on described top.

In middle section, the cover plate 8 be made up of the material identical with lath 6 is shown above described inflow funnel 1, described cover plate passes downwardly through rib structure and strengthens, and on described rib structure, plug-in mounting is to the comb inserts (Recheneinsatz) 9 of downward-extension.Described comb inserts 9 has trapezoidal shape on the horizontal line of vision vertical with the longitudinal direction of floor drain, and described trapezoidally have narrow limit above, and have broadside below.Described trapezoidal on forward and backward respectively six comb teeth (Zinken) 10 are installed about described line of vision, described comb tooth has the elongated cross sections profile (in vertical cutting plane) holded up slightly be obliquely installed, and is arranged on staggering in couples and mutually in three planes.A pair comb tooth is above mutually the most close, and a pair comb tooth furthest apart below.

Comb inserts 9 forms a kind of especially for washing away with waste water during shower and keeping the filtration of the hair hung on comb tooth 10 thus.These hairs can be left behind from comb tooth the end via comb tooth 10 after taking off the cover plate 8 with comb inserts 9, thus comb inserts 9 is easy to clean especially.Here comb inserts substantially covers the whole flow cross section of union 2 generally and can process all waste water thus, and suitable with the shape of flow cross section, and this also will describe in detail according to Fig. 4 and Fig. 5.

Finally, with comb inserts 9 unlike, cover plate 8 is symmetrical, and as shown in FIG., also can similarly be plugged on comb inserts 9 when rotating 180 ° relative to vertical axis.In other words, as also will described in detail below, load if groove profile sections 5 rotates 180 ° of ground together with inflow funnel 1 around identical vertical axis, then however still can guarantee that the words identification shown in Fig. 1 cover plate 8 upper right side or the decorative pattern do not illustrated keep left and right to coincide here.

In fig. 2, the parts shown in Fig. 1 fit together mutually, and in addition, union 2 (when retainer ring 4 inserting) inserts containing pipe 11, and flange 12 is given prominence in the horizontal direction on the upper end of containing pipe.Flange 12 and flow into that the top 3 of funnel 1 has rectangular elongate similarly and slightly become the structure of basin shape here, and partly hold described top 3 when union 2 inserts completely.

The outward flange of flange 12 is provided with sealing mat 13, and described sealing mat is injection-moulded on the die casting of containing pipe 11 and flange 12 formation.Described sealing mat extend out to significantly more than flange 12 towards all horizontal side and is connected with the diaphragm seal existed in shower region, and described diaphragm seal is arranged on below ceramic tile usually.

Fig. 3 illustrates the parts identical with Fig. 2, but wherein sealing mat 13 part below upwards turns down 90 °.Corresponding installment state is shown specifically in figures 4 and 5.In addition, for the sake of clarity Fig. 3 eliminates Reference numeral.

In figures 4 and 5, floor drain and vertical wall are installed adjacently, and described wall just schematically shows here and represents with 14.Fig. 4 illustrates the central cross sectional view through wall dewatering installation, described sectional view is perpendicular to wall 14 and thus perpendicular to the longitudinal direction of groove section bar 5, top view shown in Fig. 5 lower area, and in upper area, namely from the cutting plane of Fig. 4 upwards, horizontal cross is shown, have in sectional view the top at comb inserts 9 and cutting plane between the comb tooth 10 of central authorities, this cutting plane is below flange 12 and in the region of the vertical overlapping portion of union 2 and containing pipe 11 in other words.

On Fig. 4, the preassembled ceramic tile 15 having and determine thickness can be seen in the right of wall 14, and seamless floor 16 can be seen around flange 12 and containing pipe 11 below ceramic tile.Described seamless floor is also shown in the upper part of Fig. 5.The upper part of Fig. 5 also illustrates the circular cross-sectional profile of containing pipe 11, but also show the part of the circular arc of the cross-sectional profiles of union, this circular arc shaped portion is only distributed on the angular range less than 180 °, and this part is concentric and form fit with containing pipe 11 in this region.The region of this circular arc is arranged on the right, and the longitudinal direction along groove section bar 5 on the relative side of on the left side is provided with smooth section.There is bending transition part in (in Fig. 5 above and below) between smooth section and the section of circular arc, but described transition part along with leave arc sections section distance increase and retrude is left the Internal periphery shape of containing pipe 11 and is formed gap relative to containing pipe.

In addition, can also see at these two accompanying drawings, flow into the top 3 of funnel and also have cover plate 8 and groove section bar 5 to be biased prejudicially relative to the circular cross section of containing pipe 11 thus to the right.The axis of symmetry of containing pipe 11 is described vertical axis here, and these parts can rotate 180 ° around this vertical axis, then (except wall 14 and ceramic tile 15) can be just the same be arranged in containing pipe 11.Due to this circular symmetry, this situation is even for arbitrarily angled all applicable.Shown in these two figure, in the current situation, in the scope of these possibilities, have selected distance wall 14 position farthest, but when ceramic tile 15 is very thin or flange 12 and containing pipe 11 are arranged on more when the position of wall 14, also can select the position of rotation 180 °.

Fig. 4 particularly shows, by select union 2 with the right comparatively distant positions being installed on the rhone part on the upside of union of remainder, the substantially concordant installation site relative to ceramic tile 15 can be realized, although flange 12 and containing pipe 11 stretch into below ceramic tile 15.Here on the one hand importantly, the cross-sectional profiles of union 2 has smooth portion's section, and important the also having of another aspect, the parts that inflow funnel 1 is positioned at above do not protrude from union.Thus, flow into funnel always upwards to take out in the diagram or insert when assembling.

In addition can see, between smooth portion's section of union 2 cross-sectional profiles and arc sections section, the transition part of retrude is used for the gap realizing union in containing pipe 11.In the shown situation, only form described gap to the left, this is because, as mentioned above, have selected position the most on the right side here.But also easily can imagine the position obviously more kept left, and the rotation of 180 ° need not be carried out for this reason.When arranging the rigging position of rotation 180 °, be suitable for same situation, but now there is accurate adjustment reversed left to right accordingly.

Can also see, the angular deviation about vertical axis between the parts that all and union of containing pipe 11 and flange 12 and union 2 and floor drain is connected can easily be compensated.In addition, relative position vertical between them is also adjustable, and its mode is, with different distance inserting retainer rings 4 and thus with different degree of depth Inserting Tube joints 2.

Can see in the diagram, although union 2 is in offset maximum position to the right, retainer ring 4 still completely covers the gap between union 2 and containing pipe 11 substantially, and substantially seals the space between them thus.

In addition, can also see in the diagram here, sealing mat 13 establishes good sealing relative to wall 14 because sealing mat on wall in upwards the digging below of ceramic tile 15 (see digging position in Fig. 3).At opposite side, sealing mat 13 continues and is connected with the diaphragm seal in all the other regions of shower set between seamless floor 16 and the ceramic tile be located thereon.Therefore, even if when such as having water to flow in the gap in the transition part of ceramic tile outside groove or inflow funnel, residual leakage does not have obvious impact yet.

Fig. 4 and Fig. 5 finally illustrates, the comb tooth 10 of comb inserts 9 is form fit relative to union 2.In other words, can to see in the part on Fig. 5 in the middle of these comb teeth 10 and below plane, the length wherein pointing to the comb tooth on the right side is determined according to its outer degree.Explain tooth of combing on the right side of Fig. 4 sectional view thus and why there is different length.Generally, comb inserts 9 forms guide part when assembling cover plate 8 and prevents cover plate from tilting.
